As a unit of change, cocoa beans and copper bells were used, material that was also used for ornamental works, as well as gold, silver, jade, sea shells and colored feathers.
Egyptian agriculture was linked to the flood of the Nile and the silt deposited on the ground, turning it into a green and fertile mantle. They mainly grew cereals (barley, wheat), legumes and vegetables (leeks, lettuce, onions, garlic, cucumbers, radishes, beans, chickpeas) and fruits (melons, grapes, dates, figs). Some invading people brought new species such as apples, olives and pomegranates. In addition, pears, peaches, cherries and almonds appeared during the time of the Greek pharaohs. To make fabrics and ropes, the farmers also cultivated the linen.
